ATTORNEY Patented Sept. 17, 71 946 UNITED STATES "PATENT OFFICE2,407,770 LIQUID AIfPLICATOR I Isabelle H. Daniel, Los Angeles, Calif;Application March 18, 1943, Serial No. 479,611

This invention relates to means and methods for applying paints,lacquers, andother liquids and semi-liquids to tubes, pipes, etc., andto all kinds of rounded, flat and irregular surfaces.

The invention has been found most useful in applying lacquers and thelike over labels and identification stickers upon tubes, conduits andcables. All varieties of pipes and tubes used in a completedairplane'are marked by a variety of colored labels which are stuck tothe pipes and tubes by an adhesive of some kind. These labels must beprotected so that the pipe or tube does not lose its identification,therefore, the label and a marginal portion of the pipe or tube adjacentthereto is coated with a transparent lacquer.

The device of this invention is designed to quickly and evenly apply thelacquer to the labels and near portions of adjacent surfaces, and makinga weather-seal that is very satisfactory in accordance with thespecifications of the airplane industry.

One of the principal objects of the invention is to present a liquid orsemi-liquid coating device that applies the liquid or semi-liquid to thesurface to be coated by a rolling action, means being convenient toremove all the surplus liquid or semi-liquid from the surface as samehas been tho-roughly and evenly covered.

Another object is to provide a paint or lacquering device that is easyto be operated by unskilled hands, efiicient in operation, simple inconstruction, and economical to manufacture.

Other objects, advantages and features of my invention will appear fromthe accompanying drawing, the subjoined detailed description, thepreamble of these specifications and the appended claims.

Applicant is about to illustrate and describe one of the forms of herinvention in order to teach one how to make and use the same, but it isto be understood that the drawings and description thereof are not tolimit the invention in any sense whatsoever, except as limited by theappended claims.

In the drawing:

Fig. 1 shows the invention in side elevational view, with portionsthereof bro-ken away to show interior structural details.

Fig. 2 is a plan view with the cover or lid re-.

moved.

Fig. 3 is an elevational view showing the results obtainable when theinventive device is properly used.

The device, as illustrated, comprises a base or 2 Claims. (01. 91 -27)well unit I and a cover or lid 2'; the base having a bottom wall 3,short end walls 4 and 5, andside walls 6 and 1, all the walls preferablybeing integral to form a liquid well 8. The cover has the integral top,and side depending walls 9 l0, ll,

12 and I3 respectively, to form an inverted. receptacle-like protectoradapted to fit the top edges of the side walls of the base and protectall the elements mounted near the top thereof. 'In order that the coverwill form a fairly good hermetic seal with the base and preventevaporation of the liquid in the well, the depending sides of the coverare rabbeted at I4 so as to provide a shoulder to receive the top edgesof the base, as shown. A chain or cord I5 holds the cover near the basewhen the cover is removed.

The bottom of the base I has a short tube or socket l6 welded or :brazedthereto, into which is threaded the stem of a wing nut H. In the bore ofthe socket is one end of an offset rod l8, this rod extending from anysuitable support, such for instance, as the wall of the building, tabletop, work bench, or from some part of some machine that might be used inconjunction with the device of this invention. The purpose of the tube16 is to provide a pivot for the device so that it can be adjusted to aninclined position to facilitate its usefulness, and especially when itis an advantage to tilt the device for lacquering some odd shaped pipesand rods.

On the inner side of each wall 6 and 7 there is an embossed portionhaving parallel ribs l9 and 20, these ribs forming a rounded bearing 2|where they join together at their lower ends. The space between the ribsprovides a guideway 22 to accommodate the axle 23 of a roller 24. Thisconstruction allows the roller to be removed readily from the well forcleaning and replacement. Wrapped around the curved periphery of theroller is a felt pad 25. In thesurface of the roller is an elongatedcross slot 26, this slot being of such a size that it will snuglyreceive the ends of the felt pad and thus hold the pad tautly onto theroller in a manner that it can be removed entire base and lid may becast from metal or formed from plastics, if desired. The roller may bemade of plastic or made of wood. The entire base can be molded as asingle unit.

When the device is used for coating lacquer around a pipe and over alabel that has been cemented thereto, the cover 2 is obviously removedand the pipe placed at or about the position 3| as shown in dotted linesin Fig. 1 of the drawing:. If'thewpipe is turned as indicatedaby, thearrow: the roller 24 will rotate as-ihdicatedby its arrow, this rollingmotion will cause the felt 25 to carry lacquer upwardly from the welland contact the surfaces of the pipe 3| which are brought into contactwith the felt pad. Since the felt is usually wet with lacquer,becausezof a previous use, one complete rotation ofthe. pipe. willdeposit an even film of lacquer around the pipe. When this operation hasbeen completed, the p pe is brought into contact with thestationarygbrush. 27 and given a twist to remove all surpluslacquer fromthe pipe. Fig. 3 shows a pipe. 31 that hasbeen treatedby applicantsdevice. The lacquer, indicated at 32, completely covers a;labe1 33 whichhasbeenzpreviously cementedto the pipe, Note that the. lacquer. also,covers aportion. of the pipe. beyond the confines ofcthe;

label.

Having. thusdescribed: my, invention,. what is claimed as new anddesired to be'secured by Letters Patent is:

1. In a device for coating a liquid substance on the outer surfaces ofpipe and the like, the device comprising a base having a bottom, opposedupstanding end walls, and upstanding side walls to form a reservoir forliquid, a roller with an absorbing covering having its ends removablyjournalled in the side walls and positioned so thatgtop;portionsthereof: extendiabove' the tops of'the side walls and its=bottomportionsdip into the reservoir, a cylindrical brush having long bristlesand rotatably mounted for adjustment to.-afixed operative position on anaxis mounted in the'side walls so that the longitudinal axis ofboth.roller. and; brush are parallel, the roller and brush being sospaced apart that their near surfaces can conj'ointlysupport the pipe tobe coated and so'. that when the pipe is rotated the roller is rotated.

2.,The device. recited in claim. 1-. whereinithe base. has, asockehfixed to the underside thereof, a rod inthe sockethaving an endtobe extended and fixed to asupport, and. a finger adjustable meansforsecuring, thev rodin the socket, said socket. allowing. thedevice to.be. adjusted; around the rodzand .be tiltedto. an desiredangle.
